Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.

| 23:0 | gpio_int_polarity | Controls the polarity of edge or level sensitivity that can occur on input of Port A. Whenever a 0 is written to a bit of this register, it configures the interrupt type to falling-edge or active-low sensitive; otherwise, it is rising-edge or active-high sensitive. 0 Active-low (default) 1 Active-high
